HP LaserJet Pro MFP 3101fdw – Firmware Update Error 8AF30001

[A_Gayathri]

The error code 8AF30001 during a firmware update indicates that the device has run into a firmware‑related fault, typically during download, validation, or installation of the firmware image. 

 Troubleshooting Steps:

1. Basic checks before retrying firmware

• Verify correct firmware file

  • Make sure you are using the exact firmware for the HP LaserJet Pro MFP 3101fdw and the correct product variant.
  • Always download the latest firmware from the printer’s support page or via HP app, as appropriate.
  • Using the wrong or corrupt firmware image is a common cause of update failures. 
    
    

• Check connectivity and environment

  • If you update via network:
    • Ensure the printer is on a stable wired or wireless network.
    • Avoid VPNs, firewalls, or content filters that may interrupt or alter the firmware file.
  • If you update via USB:
    • Use a reliable USB cable and port.
    • Do not use USB hubs or long extension cables.
      
      

• Power stability

  • Ensure the printer is on a reliable power source (preferably direct wall outlet).
  • Avoid power strips that may drop voltage when other devices switch on.
    
    

2. Restart and clear queues

• Restart printer

  • Turn the printer off using the power button.
  • Unplug the power cord for at least 60 seconds.
  • Plug it back in and power on.
  • HP devices use a restart to re‑diagnose internal issues and may clear temporary firmware errors.
     

• Clear print queue

  • On your computer, clear all pending print jobs.
  • A stuck job during firmware communication can sometimes trigger update failures.
    
    

3. Use the recommended driver / app path

• Update via HP app

  • Open HP App.
  • Select your 3101fdw.
  • Go to Printer Settings or Advanced settings → Firmware or Updates.
  • Let the app check and push the firmware update. The HP app handles model verification and signed firmware delivery, reducing corruption and mismatch risks.

4. Retry firmware update with a fresh file

If you update using a PC and local file:

1. Re‑download firmware

   • Delete the old firmware file.
   • Download again from the official HP support page for your exact model.
     
     

2. Update via Embedded Web Server (EWS)

   • From a browser, open the printer’s EWS and use the firmware update section.
   • Upload the newly downloaded firmware file.
   • Do not interrupt power or network during the process.
